We're still waiting for our first look at "Thor" star Chris Hemsworth in costume as Marvel's god of thunder, so when we snagged the actor on the red carpet for "The Last Song" (featuring his brother, Liam Hemsworth), we managed to coax a few details out of him about the look he'll be sporting for the role.

Along with growing his beard out and donning a blond wig, the actor said a big part of his prep for the role involved lessons on the correct pronunciation of Thor's mighty hammer, Mjolnir.

"It's a pretty impressive costume, and I think anyone who put it on would look pretty cool," Hemsworth told MTV News.

The actor noted that he's adopted "semi-blond eyebrows and beard" for the film, and said they're currently 3/4 through filming at the moment.

"I have nice long, blond wig which they throw on every day," he said.

Hemsworth also talked a bit about wielding Thor's mighty hammer, Mjolnir — specifically, the importance placed upon pronouncing its name correctly.

"There's many different versions of pronouncing that thing," he laughed. "The rehearsal process was mainly about how do we pronounce that word."
